OIL BURNER Original application filed February 16, 1927, serialno.168,493 .mviiieala ainns application filed December 15, 1928.

This application is a division of our prior application, Serial No. 168,498, filed February 16, 1927.

Our invention relates to vaporizing oil burners, such as are used for burning liquid hydro-carbons. These burners consist of a vaporizing coil connected to an oil supply,

the vapor generated in the coil being delivered through a vapor-discharge or burner nozzle, producing a flame from the heat of which the vaporizing coil becomes suificiently heated to convert its contents into an unstable gas or vapor. A casing is provided over the vaporizing coil to prevent its be coming too cold.

One difiiculty with such oil burners as heretofore constructed is that the burner nozzle becomes clogged with flakes of carbon, putting out the flame. This required that the nozzle be cleaned, before the burner could be again lighted. In accordance with our invention, the burner nozzle is so constructed that it cannot be clogged by flakes of carbon- The various features of novelty which characterize our invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of our invention, reference maybe had to the following description taken in connection with the accompany- I ing drawing, in which Fig. 1 is a View of a burner with parts broken away having a burner nozzle constructed in accordance with our invention; Fig. 2 is a perspectiveview of our burner nozzle, and Fig. 3 is asectional view of the burner nozzle of Fig. 2.

Referring to the drawing, a source of oil (not shown) isconnected to a valve 2, to which the pipe 3 is also connected. This pipe after running the full length of the burner is bent in a coil 4 back toward the left with a spring effect between the portions of the pipe extending in opposite directions. The pipe then extends back to the left parallel to the pipe 3 and has connected to the end thereof an elbow 5 into which is screwed a burner nozzle 6, which is directed toward the vaporizing coil 4. The vaporizing coil is removably supported on a base member 7. A casing 8 having end walls 9 is detachably supported pipe where it bends back on itselfgtakes care casing are Welded'to the main portionofthe Serial no. 326,178. L p v on the base memberand'surrounds the vaporizing coil. Thecasing is provided with a saddle 2O over the pipe for holding thefp p'e, ln plac'e'." The'spring eflt'ect-of the of the difference in expansion andcontraction betweenthe casing and the pipa as the burnr er heats when lighted; and subsequently cools when extinguished. The enawanse of the casing The casing is provided with openlngs 13 to admit air to th'einterior ofthe casplace. A hood 14 is pivotally mounted on the base member This hood permits easy access to the burner nozzle'6, so that the same may be lighted. A hollow stiffening member 15 is placed around the pipe 3.

The burner nozzle 6 has an enlarged cylindrical portion 16 which is screw-threaded into -ing'so that complete combustion will,'take,

the elbow 5, and a cylindrical portion 17 of smaller diameter extending into the elbow.

A hole 18 of substantially uniform diameter extends longitudinally of the nozzle. The portion 17 of smaller diameter has a plurality of holes 19 extending therethrough and communicating with the hole 18. The holes 19 are at right angles to the hole 18 and are c of substantially the same diameter as the hole 18. It will be readily seen that with this construction, a flake of carbon entering any of nozzle, as all of these holes are of the same size. stopped up, there must be an accumulation of carbon flakes filling up the elbow'5 and cov-. ering all the holes 18 and 19 in'theburner nozzle. The nozzle is shown as made of a single piece of metal.

We desire it to be understood that our invention is not limited to the particular arrangement shown and described and we aim in the appended claims to cover all modifications which do not depart from the spirit and scope of our invention.

What we claim as new and desire to secure by Letters Patent of the United States, is:

the holes 18 or 19 will be blown through the I I In order that our nozzle be entirely 1. In an oil burner, a burner nozzle com- I hole of substantially uniform diameter extending therethrough, said portion of small diameter having a plurality of holes of substantially the same diameter as said first mentioned hole extending therethrough and communicating with said first mentioned hole.
